Abstract
An electric-hydraulic antilock braking system (ABS) installed in a trailer is coupled with a tow vehicle to facilitate controlled braking of the trailer. A trailer in-cab controller (TIC) monitors vehicle networks for diagnostic information used in determining appropriate braking actions to be taken. A communication network can interconnect the TIC, a trailer actuator controller (TAC), and an ABS controller. The ABS controller receives current tow vehicle speeds and current trailer wheel speeds, and dynamically adjusts the brakes based on the differences in the speeds. A three-way solenoid valve or an equivalent valve structure thereto allows for the ABS system to be quickly activated and deactivated.
